Depends on:
* batches (table)

Use:
This table has a list of items in a batch.
In most cases, salePrice maps to
products.special_price AND products.specialgroupprice,
pricemethod maps to products.specialpricemethod,
and quantity maps to products.specialquantity.

WFC has some weird exceptions. The main on is that 
upc can be a likecode, prefixed with \'LC\'
        ';
    }
